RADIATOR-CELL STRUCTURE.

Specification of Letters Patent.

Patented To all whom it may concern Be it known that I, HERBERT CHAMPION HARRISON, a subject of the King of Great Britain, residing at Lockport, in the county of Niagara and State of New Yorlnhave invented certain new and useful Improvements in Radiator-Cell Structures; and I do hereby declare the following to be a full, clear,

and exact description of'the invention, such as will enable others skilled in the art to more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in in elevation illustrating a pair of units made in accordance with my invention; Fig. 2 is a view similar to Fig. 1 showing the parts of one of the units in their disassembled condition; Fig. 3 is an end elevational view of a plurality of units illustrating the oilset ends of the plates in order to form the water passages between the units; Fig. 4 is an elevational view of one of the plates separating the double row of cells of which a unit is composed; and, Fig. 5 is an enlarged detail sectional view illustrating the formation of the cells.

-In carrying out my invention, I fold a metal plate 1 upon itself to form the partition or plait 2, then bend the metal outwardly at an angle of 120 to said partition 2, and at the point 3, a distance equal to the length .of the partition 2, I bend the metal inwardly at an angle of 120, while at the point 4, at a distance again equal to the length of the partition 2, I'again form a second partition 2 and repeat the foregoing operations until a suflicient niui'iber of partitions have been formed to provide the requisite number of cells. I further take a similar plate 5 and similarly form partibe first folded upon itself an tions 6 and outward bends 7 therein, as will bev clear from the drawings. I also provide a division plate 8 which is bent inwardly and outwardly to itself at angles of 120 at the points 9, and along the bent edges at intervals, I suitably perforate the said plate 8 to form the projecting ears 10, as shown. The said plate 8 is located between the two plates 1 and 5 in such manner that the partitions 2 and 6 fit respectively between the ears or'projections 10 on the plate 8, and thus form the double rowof cells or units 11, as shown.- The rojecting angles 7 of the'plates alternate with the inwardly turned angles 13, so as to form a zigzag surface. The ends of the late 1 may then re versely folded in order to form the ocket 16, and the end of the plate 8 may be olded upon itself, then reversely folded to form the pocket 17, and again folded in'an opposite direction to form the pocket 18, as best shown in Fig. 1. In the pockets 16 and 18 thus formed, I may fit'the strip 19 and in the pocket 17, I may fit the bent over end 20 of the plate 5. A similar unit made from three similar plates may be assembled in close relation to "the first mentioned unit, whereupon the projecting angles 7 of the one unit will come opposite the inwardly extending angles 13 of the other .unit' to form the zigzag water passage 22, as shown. The said zigzag water passage is, of course, longer than any straight passage could be between the same cells, and therefore, the water is subjected to a greater cooling action in this construction than would otherwise be the case. Further, the fact that there is only a single thickness of metal 8 between the cells lfi enables the structure to be lighter than is the case when a doublethickness is employed, and the partitions 2 and 6 combined with theeaZs-m aflford an exceedingly strong and compact structure The said plates 1, 5 and 8 w on assembled,

loo

may be secured together in any suitable manner, a convenient way being the dipping of the edges of the same in a bath of solder and the said units, when formed, mayfbe art The indi\ idnal units may be separated in any suitable manner, as by placing spacing material between them or the extreme edges may be off-set as illustrated. at 25 in Fi 3, in order to form the water passages It is obvious that those skilled in the art may vary the details of construction as Well as the arrangement of parts without departing from the spirit of my invention and therefore I do not wish to be limited to the above disclosure except as may be required by the claims.

1. ln a radiator, a unit comprising a pair of opposed zig-Zag outer plates folded to provide partitions at their reentrant portions, and an intermediate zigzag division plate engaging said partitions to provide two rows of polygonal cells separated by a single thiekness of metal. I

2. in a radiator, a unit comprising a pair of opposed zig-zag outer plates folded to provide partitions at their rentrant portions, and an intermediate division plate provided with pairs of projections extendtions, an intermediate zig-zag division plate engaging said partitions to provide two rows of polygonal cells separated by a single thickness of metal, and means for closing the end cells of the said rows.

4. In a radiator, a unit con'zprising a pair of opposed zig-zag outer plates folded to provide partitions and provided. with end pockets, a zig-zag div'sion plate'engaging said partitions to provide two rows ol polygonal cells separated by a single thickness of metal, and a closing strip extending within said pockets for closing the end cells of said rows.

5. In a radiator, the combination of a plu rality of units each comprising a pair oli opposed zig-Zag outer plates folded to provide partitions at their reiintrant portions, an iin'ern'iediate zigzag division plate ongaging said partitions to provide two rows of polygonal eells separatml by a single thickness of metal, and means for spacing said units apart with the projecting portions of the zig-Zag outer walls of the several units opposed to the re'entraut portions of the zigz agwalls of adjacent units.

In testimony whereof, ailix my signature, in presence of two Witnesses.

HERBERT CHAMPION HARRISON.
